Overview

Package factory can set up a scheduler. This code is here instead of plugin/cmd/scheduler for both testability and reuse.

func NewConfigFactory added in v0.7.0 

func NewConfigFactory(
	schedulerName string,
	client clientset.Interface,
	nodeInformer coreinformers.NodeInformer,
	podInformer coreinformers.PodInformer,
	pvInformer coreinformers.PersistentVolumeInformer,
	pvcInformer coreinformers.PersistentVolumeClaimInformer,

func RegisterPriorityFunction2(
	name string,
	mapFunction algorithm.PriorityMapFunction,
	reduceFunction algorithm.PriorityReduceFunction,
	weight int) string

RegisterPriorityFunction2 registers a priority function with the algorithm registry. Returns the name, with which the function was registered. FIXME: Rename to PriorityFunctionFactory.
